Re: PowerApps Portal - Digital Signature available?
As you appear to be missing the item in the metadata dropdown, you may have to update the Solution Files for your Portal (and also Possibly the Portal as well) see the prerequisites on the previous link (has the required versions etc). Also note, this is still a preview feature so Microsoft does not recommend it for Production use at this stage.
Where customers have asked for signatures from the portal, we have usually been able to avoid an actual signature based on:
- the user is logged in (authenticated), and
- we have a tickbox saying "I agree", and
- behind the Entity Form etc we have metadata set to save the Portal user into a field on the record and also the date-time. (and can also add another one for Submitted from Portal)
So we have a record that is timestamped, and we capture the user/contact making the declaration, and this record is created by System (so not a normal user just creating the record).
